Ok, maybe Penelope doesn't have a six-pack, yet. But for the first time, we can now feel her abdominal muscles flexing. Granted, they are covered with a nice layer of fat, but they are definitely there. They are easiest to feel when she is being held in a seated position or when she is lying on her back and lifting her legs. When she flexes her abs, they feel rock hard. It's pretty awesome. I think we're going to start her on crunches soon. And I'm totally getting her a thigh-master for Christmas. Feel the burn, baby.
